Diamond Cuts: A Guide to Shape, Sparkle & Style

When choosing a diamond, the “cut” plays a bigger role than many realize. While “shape” refers to the overall outline—like round, oval, or pear—“cut” defines how well the diamond’s facets reflect light. It's the artistry of proportion, symmetry, and polish that gives each stone its brilliance.

Here’s a guide to the most popular diamond cuts to help you find your perfect match.

Round Brilliant Cut

Timeless and iconic, the round brilliant cut maximizes light return and sparkle. With 57-58 carefully calculated facets, this classic choice is beloved for engagement rings.

Tip: Choose “ideal” or “excellent” cut grades for maximum brilliance.

Princess Cut

This square-shaped beauty blends modern style with fire. A popular alternative to the round cut, princess diamonds have exceptional sparkle at the corners too.

Tip: Opt for protective prongs to safeguard the pointed corners.

Cushion Cut

Known for its vintage charm and soft edges, the cushion cut (or “pillow cut”) combines brilliance and clarity in a square or rectangular silhouette.

Tip: A great option for showcasing color in fancy diamonds.

Marquise Cut

Elongated and regal, the marquise cut creates the illusion of longer fingers and maximizes carat size visually.

Tip: Look for symmetry and consider accent side stones for balance.

Emerald Cut

Sleek and sophisticated, emerald cuts highlight clarity over sparkle, thanks to their step-cut design and large table.

Tip: Choose higher clarity grades, as inclusions are more visible.

Radiant Cut

Combining the brilliance of a round with the geometry of an emerald, the radiant cut is durable and vibrant—ideal for active lifestyles.

Tip: Pairs beautifully with a variety of side stones.

Pear Cut

A graceful blend of round and marquise, the pear cut is elegant and elongating, often worn with the point facing the heart.

Tip: Symmetry is key; look for balance between the rounded and pointed ends.

Oval Cut

Similar in brilliance to a round diamond but with an elongated shape, the oval cut offers a contemporary, slimming effect.

Tip: A halo setting enhances both size and sparkle.

Asscher Cut

Vintage and geometric, the Asscher cut features deep facets and a square shape. Known for its art deco appeal, it offers a bold, architectural look.

Tip: Best displayed in solitaire or pavé settings for full impact.

Baguette Cut

Commonly used as side stones, the step-cut baguette offers understated elegance with clean lines and minimal sparkle.

Tip: Often found flanking larger center stones or in eternity bands.

Trillion Cut

Triangular and striking, trillion cuts are typically used as accents but can also serve as a unique centerpiece.

Tip: Look for V-shaped prongs to protect pointed edges.

Heart Cut

Romantic and symbolic, the heart cut is a favorite for Valentine’s Day and anniversary jewelry. Its symmetry makes or breaks its beauty.

Tip: Ideal as a solitaire in pendants or rings with minimal embellishment.
